23. Internet Protocol version 6 (IPv6)
    • Every device on the Internet is assigned an IP
    address for identification & location definition
    • Proposed in 1998 by Internet Engineering Task
    Force (IETF)
    • Successor to IPv4
    • Uses 128-bit address (instead of 32)

24. Packets
    • the basic unit of transport for digital communications networks
    • A sequence of bytes (1's and 0's) that contain a source address,
    destination address, and body
    • headers === metadata, i.e. sender/receiver address
    • body === the information the sender wants the receiver to have,
    must be less than 64KB

26. Dynamic Host Configuration Protocol
    (DHCP)
    • Protocol for dynamically assigning IP addresses
    • Used to control the network configuration of a host
    through a remote server
    • Consists of various message types, i.e.
    DHCPDISCOVER, DHCPOFFER, DHCPREQUEST
    • the IP address assigned by server to client is on a
    lease

27. Wi-Fi / WiFi
    • Any "wireless local area network" (WLAN) product
    based on the Institute of Electrical and Electronics
    Engineers (IEEE) 802.11 standards
    • Less secure than wired connections
    • First version of the 802.11 protocol was released in
    1997
    • Suggested method of security is WPA2
